When the leading edge of the tonewheel notch passes the tip of the CKP, the following occurs: The interruption of magnetic field causes the voltage to
switch high resulting in a signal of approximately 5 volts.
When the trailing edge of the tonewheel notch passes the tip of the CKP, the following occurs: The change of the magnetic field causes the signal voltage
to switch low to 0 volts.
The Camshaft Position Sensor (CMP) also provides a signal to the Powertrain Control Module (PCM) at all times when the engine is running. The PCM
uses this CMP information primarily on engine start-up. Once the engine is running, the PCM uses the CMP as a backup sensor for engine speed.
